š§µ IT'S THE BIG ONE

Breakthrough Listen, ESA, and the Chinese are all preparing to disclose details about the detection of an alien techno-signature from Alpha Centauri, named BLC-1. This isn't some made up shit, actual scientists with government funding have done it.

š§µ Can a computer running on zero-point energy live forever?
Anonymous at Sun, 20 Oct 2024 16:41:23 UTC No. 16441362
In theory, if we or artificial superintelligence ever invents a way to tap into zero-point energy, which would be an eternal energy source if I'm not mistaken, would any other physical phenomena or limitations make it impossible for a computer floating in the void of space expelling its waste heat out to stay turned on literally forever? I'm thinking perhaps a false vacuum decay would destroy it eventually (or destroy you eventually if mind uploading was possible and you lived inside that computer). Chatgpt is confusing me, though, suggesting that the heat death will make expelling waste heat impossible for some reason (I don't get that) and suggesting that the buildup of errors during to random quantum fluctuations would eventually outpace your ability to correct those errors. This also doesn't make sense to me, but maybe someone can explain.

š§µ why does quant trading make any money at all?
Anonymous at Sun, 20 Oct 2024 15:25:35 UTC No. 16441288
The moment you have an algorithm/model that generates returns above market average, you are incentivized to 1. keep it secret, and 2. put as much money as possible into it. Because its literally free money. All you need is capital. If you can make a dollar you can make a billion. But if you are making billions, that probably affects the market itself, bringing the returns from your algorithm/model back down to market average.
So it doesn't make sense that there can be multiple competing companies and algorithms/models, because if they are consistently generating above market average returns, why are they not putting more money into it? But there are. What? Can /sci/ explain?

What's the best way to improve the math literacy of a community?
I keep thinking that the lack of applications is very detrimental to the perception of it.
Perhaps a good approach would be to give what is learnt practical applications immediately, this would probably change the perspective of it greatly.
Personally I was a math hater, until I started studying code, then I saw how all that I had learned could be used and started to love em.

>scientific community throughout history is made out of bored nobles and aristocrats that can fund their own researches
>modern scientific community is made out of starving graduates clinging to the old boomers representing what's left of the old scientific community, selling their integrity for a crumb of ibternational fame and the possibility to see their meaningless studues published
Same goes for everyone who has a degree, and it's especially true with philosophy/letters/history. There's no prestige left because too many try to be academics these days.

š§µ Vacuum energy density and relativistic effects
Anonymous at Sun, 20 Oct 2024 13:57:48 UTC No. 16441192
One of the common proposals for resolving the discrepancy between the standard model prediction of vacuum energy and the observed value is yet-unaccounted for destructive interference of virtual particles that causes the vacuum energy to reach a small but non-zero value. A common objection to this is why the value is none-zero.
Is it possible that the value actually is zero, but due to relativistic effects, the destructive interference is not complete? Imagine for a moment that a stationary observer is watching a standing wave on a string. This can be imagined as a wave travelling down the length of the string, reflecting back, and causing constructive and destructive interference with the wave travelling down.
An observer moving at close to c travelling past the stationary observer would see the events in a different order due to the non-simultanity of events and length contraction etc. So they may well observe a different standing wave pattern.
Is it possible that this same phenomenon is responsible for our observations of there being a none-zero vacuum energy constant? The local vacuum energy actually is zero or very close to it, and at cosmic scales, due to the increased velocity of distant objects, they appear to us to have a none zero vacuum energy which actually further increases their acceleration, thus also explaining why distant objects appear to accelerate proportional to their distance?
Interested in your thoughts, thank you gentlemen

Why is the sum of exterior angles of a polygon always 360 degrees but the sum of the interior angles is 180*(p-2)? (p being the number of points it has.)
Suppose you have a decagon, one person walks the interior perimeter and the other exterior perimeter. They are 1cm away from each other when they do this. They make more or less the same turns but one is considered to have turned a total of 360 degrees and the other 1440 degrees. Why?

I wonder what proportion of "paranormal experience" is genuinely under analysed scientific phenomena and how much is just the wind or whatever.
My guess would be days in the age of the earth because a huge proportion of people a creepy story even if they're happy to admit it's a bit silly. I've observed various things that gave me the creeps or a strange sense of awe.

"Now suppose that we have a point at O, at a distance s from the front surface of the glass, and another point Oā² at a distance sā² inside the glass, and we desire to arrange the curved surface in such a manner that every ray from O which hits the surface, at any point P, will be bent so as to proceed toward the point Oā². For that to be true, we have to shape the surface in such a way that the time it takes for the light to go from O to P, that is, the distance OP divided by the speed of light (the speed here is unity), plus nā
Oā²P, which is the time it takes to go from P to Oā², is equal to a constant independent of the point P. This condition supplies us with an equation for determining the surface. The answer is that the surface is a very complicated fourth-degree curve, and the student may entertain himself by trying to calculate it by analytic geometry."
Now is this as simple as
1. Set up the coordinate system:
2. Place the point O at (0, 0, -s) on the z-axis.
Place O' at (0, 0, s') on the z-axis.
3. Let P be a general point (x, y, z) on the surface we're trying to determine.
4. Express the distances:
OP = ā(x2 + y2 + (z+s)2)
O'P = ā(x2 + y2 + (z-s')2)
5. Write the equation based on the constant time condition:
OP + nā
O'P = k, where k is a constant and n is the refractive index of the glass.
6. Substitute the distances:
ā(x2 + y2 + (z+s)2) + nā
ā(x2 + y2 + (z-s')2) = k
7. Continue with this mess
I wonder if there are any practical examples of solving geometries like that? I assume this would be solved computationally so I'm interested in any matlab/python/sage code if anyone knows of stuff like this

If the Mulitverse Theory is true, does that mean the laws of physics are so different that "life" in those universes and the physical landscape look unimaginable and alien? (Like the Pennywise alien spider true form for instance) If that makes sense?

Why aren't there animals in space? What if underwater animals could exist in space? They'd swim like they would in water, except in space. Am I the only one seeing the connection between these two things? Apart from there not being any food in space, and the unlikely probability of any earth animal ever getting into space, wouldn't there be a possibility for animals to evolve into animals that can live in space? What keeps them from doing that? Why can't microbial life sustain themselves in space through something like photosynthesis or some other means?

How would you go about disposing 600 grams of Triacetone Triperoxide without detonating it. is there anyway of neutralizing it? I've looked all over the internet but I just can't seem to find any information on neutralizing it any help is appreciated. without needing to call a bomb squad (hypothetical)
š§µ probability is a meme
Anonymous at Sun, 20 Oct 2024 06:41:52 UTC No. 16440866
as long as there is not 100% likelihood there is 100% likelihood of an unfavorable outcome across an infinite series of attempts.
say for example, i had a coinflip bet. I have the options to win if i choose tails, i flip the coin an infinite amount of times and get caught in an endless loop of heads. I'm just that unlucky. probability says I have a 50% *chance* which is correct, but miraculously i have gotten heads an infinite amount of times. what happened there?
